Description

Technical Field

[0001] The present invention relates to the technical field of thermos processing, and particularly to a bottle body forming device and a forming method for processing a double-layer thermos. Background Technique

[0002] For the forming of a thermos, first, the inner and outer bottles of the thermos are stretched by means of water pressure and stamping. Then, the inner bottle and the outer bottle are sleeved, and the pre-processed bottle mouth part is inserted into the inner bottle and the outer bottle. Then, welding is carried out to complete the forming of the bottle body. However, when the inner and outer bottles of the bottle body are combined with the bottle mouth part after stretching, it is manually combined. However, the manual method not only has low efficiency but also poor quality. That is, the worker holds the inner bottle and inserts it into the outer bottle, and then inserts the bottle mouth part between the inner bottle and the outer bottle. When processing in this way, the worker usually encounters the following problems: First, when sleeving the inner bottle and the outer bottle, it is difficult to control the coaxiality of the inner bottle and the outer bottle, which easily leads to deviation after the inner bottle and the outer bottle are sleeved. When the worker then sleeves the bottle mouth part, it will be difficult for the bottle mouth part to be smoothly sleeved, and the worker needs to adjust back and forth, which affects the efficiency. Second, because there are concave grooves on the outer side of the inner bottle and the inner side of the outer bottle, and there are convex strips on the bottle mouth part, the cooperation between the two plays a role in preliminary positioning, and then it is convenient for subsequent processing. When the three are combined together, generally a certain pressure needs to be applied to make the three smoothly combine. This requires the worker to use a hammer to apply a certain pressure. However, sometimes when the worker uses a hammer to apply pressure to the bottle mouth part, it is easy to make the bottle mouth part tilt, thus damaging the bottle mouth part or the inner and outer bottles when knocking.

[0003] Based on this, the present invention designs a bottle body forming device and a forming method for processing a double-layer thermos to solve the above problems. Summary of the Invention

[0045] Please refer to Figures 1-14, the present invention provides a technical solution: a bottle body forming device for processing a double-layer thermos bottle, including a base 1, two support columns 2 are fixedly connected to the top of the base 1, a punching head 3 is arranged above each of the two support columns 2, and a support plate 4 is slidably connected to the base 1; the support plate 4 is fixedly connected with a fourth spring 24 for its reset, a fixing frame 5 is arranged behind the support plate 4, the fixing frame 5 is fixedly connected to the top of the base 1, a limiting plate 6 is rotatably connected to the fixing frame 5, and a socketing component is arranged on the limiting plate 6;

[0046] The socketing component includes a first motor 7, a second motor 8 and an unfolding group. The unfolding group is located in front of the first motor 7. Both the first motor 7 and the second motor 8 are slidably connected to the limiting plate 6; the second motor 8 is fixedly connected with a first spring 9 for its reset, a second spring 10 is fixedly connected between the first motor 7 and the second motor 8, the output ends of both the first motor 7 and the second motor 8 are fixedly connected with cross plates 11, a first clamping group and a second clamping group are respectively arranged in front of the two cross plates 11, and the first clamping group is located above the second clamping group;

[0047] The first clamping group and the second clamping group have exactly the same structure. The first clamping group includes two L-shaped rods 12. Both the two L-shaped rods 12 are slidably connected to the cross plate 11. Both the two L-shaped rods 12 are fixedly connected with a third spring 13 for their reset. Both the two L-shaped rods 12 are fixedly connected with a first air cylinder 14. The output ends of both the two first air cylinders 14 are fixedly connected with a first clamping piece 15;

[0048] The unfolding group includes a fixed rod 16, two notches 19 and two inserting rods 50. The fixed rod 16 is fixedly connected with the cross plate 11 in the first clamping group. The two inserting rods 50 are respectively rotatably connected to the bottom of the first clamping piece 15. The two inserting rods 50 can push the first clamping piece 15 in the lower second clamping group to move to one side. The fixed rod 16 is slidably connected with a U-shaped rod 17. Both the left and right ends of the U-shaped rod 17 are rotatably connected with a support rod 18. The two support rods 18 are respectively rotatably connected with the two first clamping pieces 15. The two notches 19 are opened on the two first clamping pieces 15. A limiting wheel 20 is arranged inside each of the two notches 19. The two limiting wheels 20 are respectively rotatably connected with the two first clamping pieces 15. Both the two limiting wheels 20 are fixedly connected with a first gear 21. Both the two first gears 21 are engaged with a first rack bar 22. The bottoms of the two first rack bars 22 are L-shaped. The two first rack bars 22 are respectively slidably connected with the two first clamping pieces 15; both the two first rack bars 22 are fixedly connected with a seventh spring 23 for their reset;

[0049] Above the base 1, a driving assembly is provided. The driving assembly is used to drive the two stamping heads 3 to stamp the inner and outer bottles of the thermos flask, drive the limiting plate 6 to rotate when the stamping head 3 rises, and convey the stamped inner and outer bottles towards the first clamping group and the second clamping group.

[0050] When the above solution is put into actual use, the bottle mouth part is located below the second clamping group. Then, the inner and outer bottles to be stamped are both placed on the support plate 4. Then, the driving assembly is started, and the driving assembly will drive the two stamping heads 3 to descend. When the two stamping heads 3 descend, they will contact the inner and outer bottles and cause the support plate 4 to descend. When the support plate 4 descends, it will compress the fourth spring 24. At this time, the inner and outer bottles will follow the support plate 4 to descend. When the support plate 4 and the stamping heads 3 descend to the limit position, the inner and outer bottles will be formed by the two support columns 2. Then, the driving assembly drives the two stamping heads 3 to rise to the initial position. At this time, the elastic relaxation of the fourth spring 24 will drive the support plate 4 and the stamped inner and outer bottles to rise. When the support plate 4 rises to the initial position, the driving assembly will convey the stamped inner and outer bottles towards the first clamping group and the second clamping group. During the process of the driving assembly conveying the inner and outer bottles, it will also drive the limiting plate 6 to rotate 90 degrees around the fixed frame 5. Then, the first cylinder 14 in the first clamping group and the second clamping group is started. At this time, the first clamping pieces 15 will move away from each other until the driving assembly places the inner and outer bottles between the two first clamping pieces 15, and then the first cylinder 14 shortens, so that they are clamped by the first clamping pieces 15. Then, the driving assembly is reset. During the reset process of the driving assembly, the limiting plate 6 will also rotate 90 degrees around the rotating shaft until the limiting plate 6 is in the initial state (i.e., the vertical state). And the first motor 7 and the second motor 8 will also be started and drive the two cross plates 11 to rotate 90 degrees. When the limiting plate 6 is in the vertical state, the stamped outer bottle is located above the inner bottle, and the two are coaxial.

[0051] Then the staff places the inner and outer liners to be stamped above the support plate 4, and then the driving assembly drives the two stamping heads 3 to descend again, so as to stamp the new inner and outer liners. When the two stamping heads 3 stamp the new inner liner, they will press down the U-shaped rod 17. Since the structures of the first clamping group and the second clamping group are the same, the U-shaped rod 17 above the first clamping group will drive the first motor 7 to slide downward along the limiting plate 6 after being pressed down by the driving assembly (the first motor 7 and the second motor 8 are slidably connected to the limiting plate 6 through the sliders fixedly connected to the rear end). When the first motor 7 slides downward, it will drive the thermos bottle outer liner clamped by the first clamping group to descend, and will push the second motor 8 to move downward along the limiting plate 6 through the second spring 10. When the second motor 8 descends, it will drive the inner liner clamped by the second clamping group to move downward. When the second motor 8 moves downward, it will apply a certain degree of pressure to the first spring 9. When the first motor 7 descends to a certain extent (that is, when the second spring 10 is compressed to a certain extent), the second motor 8 will compress the first spring 9 to the limit position. At this time, the second motor 8 also descends to the limit position. After the second motor 8 descends to the limit position, the bottle mouth below the thermos bottle inner liner will directly insert into the bottle mouth part, thus completing the combination of the bottle mouth part and the thermos bottle inner liner. At this time, the driving assembly continues to press down the U-shaped rod 17. When the first clamping group descends until the first rack bar 22 contacts the first clamping piece 15 in the second clamping group, if the first motor 7 descends further, the first rack bar 22 will slide upward along the first clamping piece 15 in the first clamping group and compress the seventh spring 23. When the first rack bar 22 rises, it will engage with the first gear 21 and drive the limiting wheel 20 to rotate. At this time, the two limiting wheels 20 will convey the outer liner clamped by the first clamping group downward by a certain distance. Then the inserting rod 50 will contact the first clamping piece 15 in the second clamping group. The inserting rod 50 has a certain inclination. When the inserting rod 50 contacts the notch 19 on the first clamping piece 15, it will push the first clamping piece 15 to both sides. At this time, the first clamping piece 15, the L-shaped rod 12 and the first cylinder 14 in the second clamping group will all slide along the cross plate 11 and compress the third spring 13. At this time, the two first clamping pieces 15 move away from each other. Then the first motor 7 descends to the limit position. At this time, the two first clamping pieces 15 in the first clamping group also drive the thermos bottle outer liner to insert into the bottle mouth part below, and the thermos bottle outer liner will sleeve the inner liner inside. Because the inserting rod 50 pushes the first clamping piece 15 in the second clamping group to both sides by a certain distance, the outer liner will not be blocked by the first clamping piece 15 when sleeving the inner liner;

[0052] After the inner and outer liners and the bottle mouth part are sleeved, the two punching heads 3 are about to descend to the limit distance. Then, the driving assembly continues to drive the punching heads 3 to descend. When the punching heads 3 descend to the limit distance, the driving assembly still presses down the U-shaped rod 17. At this time, the U-shaped rod 17 will slide down along the fixed rod 16. When the U-shaped rod 17 descends, the support rod 18 will push the first clamping piece 15 in the first clamping group and the two L-shaped rods 12 to slide and expand along the cross plate 11. And when the first clamping piece 15 in the first clamping group expands, it will also drive the first clamping piece 15 in the second clamping group to expand. At this time, the first clamping pieces in the first clamping group and the second clamping group are all far away from each other, and the inner and outer liners and the bottle mouth part are also sleeved. Then, it can be directly removed. And the new inner and outer liners above the support plate 4 are also stamped. Then, the driving assembly drives the punching heads 3 to rise again, and then the first motor 7 and the second motor 8 are reset;

[0053] When the inner and outer liners are sleeved, the limiting plate 6 is in a vertical state, so that the inner and outer liners are coaxial. Furthermore, when the inner and outer liners are sleeved, deviation can be prevented, and it is not necessary for workers to adjust the positions of the inner and outer liners and the bottle mouth part back and forth, preventing damage to the bottle mouth part and the inner and outer liners when workers apply pressure with a hammer, improving production efficiency and reducing labor costs;

[0054] Moreover, from stamping to subsequent forming, the processing is carried out in the same process, without the need for transfer and transportation. The process is integrated, and it can also avoid damage to the inner and outer liners during the transportation process.

[0055] As a further solution of the present invention, the driving assembly includes a top plate 25 and two hydraulic rods 26. The top plate 25 is fixedly connected with two pressing rods 49. The pressing rods 49 are used to press down the U-shaped rod 17. The top plate 25 is fixedly connected to the tops of the two punching heads 3. The two hydraulic rods 26 are fixedly connected between the base 1 and the top plate 25. Electric slide rails 27 are arranged on the inner sides of the two hydraulic rods 26. The two electric slide rails 27 are both fixedly connected to the base 1. The two electric slide rails 27 are both slidably connected with connecting plates 28. The two connecting plates 28 are both fixedly connected with two second cylinders 29. The four second cylinders 29 are all fixedly connected with second clamping pieces 30;

[0056] The driving assembly further includes a transmission group, and the transmission group is used to drive the limiting plate 6 to rotate.

[0057] When the above driving assembly works, after the inner and outer liners to be stamped are placed on the support plate 4, the two hydraulic rods 26 are started. The two hydraulic rods 26 drive the top plate 25 to descend, so that the two punching heads 3 descend. When the top plate 25 descends, it will drive the pressing rods 49 to descend, so that the pressing rods 49 press down the U-shaped rod 17, and then the inner and outer liners processed last time are sleeved with the bottle mouth part;

[0058] After the punching head 3 completes the punching of the inner and outer bladders, the hydraulic rod 26 will drive the top plate 25 and the punching head 3 to rise to the initial position, and then the two connecting plates 28 will slide along the two electric slide rails 27. When the connecting plates 28 move to the inner and outer bladder positions above the support plate 4, the two connecting plates 28 stop and the two second cylinders 29 extend and retract, so that the two second clamping plates 30 clamp the two inner and outer bladders that have just been punched, and then the connecting plates 28 continue to slide along the electric slide rails 27. At this time, the transmission group will drive the limit plate 6 to rotate 90 degrees, so that the limit plate 6 is in a horizontal state, and the first motor 7 and the second motor 8 will also drive the two cross plates 11 to rotate 90 degrees, and the first cylinders 14 in the first clamping group and the second clamping group will also extend. After moving to the extreme position of the electric slide rail 27, the inner and outer liner clamped by the two second clamping plates 30 are in the middle of the first clamping plate 15, and then the first cylinder 14 is reset, so that the first clamping plate 15 clamps the inner and outer liner (after the limit plate 6 is in a horizontal state, the height of the first clamping plate 15 is slightly higher than that of the second clamping plate 30), and then the connecting plate 28 is reset to the initial position along the electric slide rail, and then the first motor 7 and the second motor 8 drive the cross plate 11 to rotate ninety degrees, so that the inner and outer liner change from a vertical state to a horizontal state, and then the transmission group drives the limit plate 6 to reset again, so that the limit plate 6 is in a vertical state, and then the punch head 3 presses the U-shaped rod 17 downward through the pressure rod 49 when punching the new inner and outer liner, so that the inner and outer liner and the bottle mouth piece are sleeved together.

[0059] As a further solution of the present invention, the transmission group includes a slide bar 31, the slide bar 31 is L-shaped, and the slide bar 31 is slidably connected to a second rack bar 32; the second rack bar 32 is fixedly connected to a fifth spring for resetting the second rack bar 32, and a second gear 33 is arranged behind the second rack bar 32, the second gear 33 is rotatably connected to the base 1, the rotation shaft of the second gear 33 is fixedly connected to a first bevel gear 34, the first bevel gear 34 is meshed with a second bevel gear 35, the second bevel gear 35 is rotatably connected to the fixed frame 5, and a belt 36 is transmission-connected between the rotation shaft of the second bevel gear 35 and the rotation shaft of the limit plate 6;

[0060] A conveying group is arranged on the left side of the transmission group.

[0061] When the above transmission group is working, after the two second clamping pieces 30 clamp the inner and outer liners completed by stamping on the support plate 4, the connecting plate 28 continues to slide along the electric slide rail 27 and drives the slide rod 31 and the second rack bar 32 to move. After the second rack bar 32 contacts the second gear 33, it will drive the second gear 33 to rotate. When the second gear 33 rotates, it will drive the first bevel gear 34 to rotate. Then the first bevel gear 34 will drive the second bevel gear 35 to rotate. When the second bevel gear 35 rotates, it drives the rotating shaft of the limiting plate 6 to rotate through the belt 36, so that the limiting plate 6 rotates by 90 degrees. And a fifth spring is fixedly connected between the second rack bar 33 and the slide rod 32, and a protrusion block is arranged on the side of the second rack bar 33. When the limiting plate 6 rotates by 90 degrees, the protrusion on the side of the second rack bar 33 contacts the base 1, making the second rack bar 33 unable to move forward. Furthermore, the limiting plate 6 will not continue to rotate after rotating by 90 degrees, and will only compress the fifth spring when the slide rod 32 continues to move until the second clamping piece 30 conveys the inner and outer liners into the first clamping piece 15;

[0062] When the first clamping piece 15 clamps the inner and outer liners, the connecting plate 28 drives the slide rod 31 and the second rack bar 32 to retreat, so that the limiting plate 6 continues to be in a vertical state.

[0063] As a further solution of the present invention, the conveying group includes a conveyor belt 37. Both idler shafts of the conveyor belt 37 are rotatably connected to the base 1. A placement groove 38 is opened above the conveyor belt 37, and the placement groove 38 is used to place the bottle mouth parts;

[0064] A positioning group is arranged in front of the conveying group, and the positioning group is used to position the bottle mouth parts and drive the conveyor belt 37 to rotate.

[0065] When the above conveying group is working, the conveyor belt 37 is used to load and convey the inner and outer liners completed by socketing the bottle mouth parts. The bottle mouth parts are placed on the placement groove 38, and the placement groove 38 is directly below the center point of the first clamping piece 15. And the bottle mouth parts are positioned by the positioning group, so that the bottle mouth parts can be coaxial with the inner and outer liners above during socketing. When the socketing of the inner and outer liners and the bottle mouth parts is completed, the positioning group will drive the conveyor belt 37 to move, and then socket the subsequent bottle mouth parts.

[0066] As a further solution of the present invention, the positioning group includes two clamping rods 39, two resisting rods 41 and a support frame 42, the support frame 42 is fixedly connected to the top of the base 1, and the two clamping rods 39 are slidably connected to the base 1; the two clamping rods 39 are fixedly connected with the sixth spring 40, the two resisting rods 41 are fixedly connected with the support plate 4, the resisting rod 41 is used to push the clamping rod 39 to move to one side, the two clamping rods 39 are fixedly connected with the third rack rod 43, the two third rack rods 43 are meshed with the third gear 44, the two third gears 44 are rotatably connected to the support frame 42, the rotating shafts of the two third gears 44 are sleeved with the first torsion spring 45, the two third gears 44 are rotatably connected with the ratchet 46, and the left and right side walls of the conveyor belt 37 are fixedly connected with the shift rod 47.

[0067] When the positioning group is working, the punch head 3 will press down the support plate 4 when it descends, and the pressure rod 49 will press down the U-shaped rod 17. When the support plate 4 is about to descend to the limit position, the inner liner and the outer liner are already connected with the bottle mouth piece, and then the hydraulic rod 26 continues to drive the punch head 3 to descend, and the resistance rod 41 will contact the clamping rod 39 and push the clamping rods 39 away from each other, thereby releasing the clamping positioning of the bottle mouth piece. The clamping rod 39 will compress the sixth spring 40 when it moves, and the clamping rod 39 will also drive the third rack rod 43 to mesh with the third gear 44 when it moves. When the third gear 44 rotates, it will drive the ratchet 46 to rotate. When the clamping rod 39 has not completely slipped out of the placement groove 38, the ratchet 46 will not move when the third gear 44 rotates. The rod 47 moves, but compresses the first torsion spring 45. When the clamping rod 39 slides out of the placement groove 38, the first torsion spring 45 will drive the pawl 46 to move the lever 47 under the elastic action of the first torsion spring 45, thereby causing the conveyor belt 37 to rotate. When the conveyor belt 37 rotates, it will drive the bottle mouth piece that has been sleeved to fall forward, and cause the bottle mouth piece in the rear placement groove 38 to move forward. Then the hydraulic rod 26 drives the top plate 25 to rise, and the support plate 4 also rises at this time. After the support plate 4 rises to a high place, the sixth spring 40 drives the clamping rod 39 to reset. When resetting, the clamping rod 39 will move from both sides of the placement groove 38 to the middle, thereby positioning the bottle mouth piece inside the placement groove 38, and the support frame 42 can support the bottom of the bottle mouth piece when the second clamping group descends.

[0068] As a further solution of the present invention, a material discharge barrel 48 is arranged in front of the conveyor belt 37 , and the material discharge barrel 48 is fixedly connected to the base 1 .

[0069] When the above scheme is working, when the conveying group conveys the bottle mouth piece that has been sleeved forward, the bottle mouth piece that has been sleeved will fall into the discharge barrel 48, thereby completing the discharge, and a through hole is provided in the base 1 below the discharge barrel 48 to facilitate the dropping of the inner and outer liner.

[0070] As a further solution of the present invention, the blanking cylinder 48 is in an annular shape.

[0071] During the operation of the above solution, the annular blanking cylinder 48 can be used for limiting, preventing the inner and outer cylinders after being sleeved from falling to other positions.

[0072] A method for forming a bottle body for processing a double-layer thermos bottle, applicable to the bottle body forming device for processing a double-layer thermos bottle described in claims 1-7, is characterized in that the method includes the following steps:

[0073] Step 1: Place the inner and outer cylinders to be processed on the support plate 4, and then the hydraulic rod 26 drives the punching head 3 to descend:

[0074] Step 2: When the hydraulic rod 26 descends, it presses on the U-shaped rod 17 through the pressing rod 49, and then the inner and outer cylinders are sleeved by the first clamping group and the second clamping group, and then the first clamping piece 15 moves away from each other;

[0075] Step 3: After the support plate 4 descends to the limit position, the positioning group drives the conveyor belt 37 to rotate, so that the sleeved inner and outer cylinders and the bottle mouth part fall into the blanking cylinder 48;

[0076] Step 4: After the support plate 4 rises to a high position, the two clamping rods 39 clamp and position the bottle mouth part in the placement groove 38;

[0077] Step 5: The second clamping piece 30 conveys the inner and outer cylinders after stamping to the first clamping group and the second clamping group, and rotates the limiting plate 6 through the transmission group.

[0078] Working principle: The bottle mouth part is located below the second clamping group. Then, the inner liner and the outer liner to be stamped are both placed on the support plate 4. Next, the driving component is started, and the driving component will drive the two stamping heads 3 to descend. When the two stamping heads 3 descend, they will contact the inner liner and the outer liner and cause the support plate 4 to descend. When the support plate 4 descends, it will compress the fourth spring 24. At this time, the inner liner and the outer liner will follow the support plate 4 to descend. When the support plate 4 and the stamping heads 3 descend to the limit position, the inner liner and the outer liner will be formed by the two support columns 2. Then, the driving component drives the two stamping heads 3 to rise to the initial position. At this time, the elastic relaxation of the fourth spring 24 will drive the support plate 4 and the stamped inner liner and outer liner to rise. When the support plate 4 rises to the initial position, the driving component will convey the stamped inner liner and outer liner in the direction of the first clamping group and the second clamping group. During the process of the driving component conveying the inner liner and the outer liner, it will also drive the limiting plate 6 to rotate 90 degrees around the fixed frame 5. Then, the first cylinder 14 in the first clamping group and the second clamping group is started. At this time, the first clamping pieces 15 will move away from each other. Until the driving component places the inner and outer liners between the two first clamping pieces 15, the first cylinder 14 shortens, so that they are clamped by the first clamping pieces 15. Then, the driving component is reset. During the reset process of the driving component, the limiting plate 6 will also rotate 90 degrees around the rotating shaft until the limiting plate 6 is in the initial state (i.e., the vertical state). And the first motor 7 and the second motor 8 will also be started and drive the two cross plates 11 to rotate 90 degrees. When the limiting plate 6 is in the vertical state, the stamped outer liner is located above the inner liner, and the two are coaxial;

[0079] Then the staff places the inner and outer liners to be stamped above the support plate 4, and then the driving assembly drives the two stamping heads 3 to descend again, so as to stamp the new inner and outer liners. When the two stamping heads 3 stamp the new inner liner, they will press down the U-shaped rod 17. Since the structures of the first clamping group and the second clamping group are the same, the U-shaped rod 17 above the first clamping group will drive the first motor 7 to slide downward along the limiting plate 6 after being pressed down by the driving assembly (the first motor 7 and the second motor 8 are slidably connected to the limiting plate 6 through the sliders fixedly connected to the rear ends). When the first motor 7 slides downward, it will drive the thermos flask outer liner clamped by the first clamping group to descend, and will push the second motor 8 to move downward along the limiting plate 6 through the second spring 10. When the second motor 8 descends, it will drive the inner liner clamped by the second clamping group to move downward. When the second motor 8 moves downward, it will apply a certain degree of pressure to the first spring 9. When the first motor 7 descends to a certain extent (that is, when the second spring 10 is compressed to a certain extent), the second motor 8 will compress the first spring 9 to the limit position. At this time, the second motor 8 also descends to the limit position. After the second motor 8 descends to the limit position, the bottle mouth below the thermos flask inner liner will directly insert into the bottle mouth part, thus completing the combination of the bottle mouth part and the thermos flask inner liner. At this time, the driving assembly continues to press down the U-shaped rod 17. When the first clamping group descends until the first rack bar 22 contacts the first clamping piece 15 in the second clamping group, if the first motor 7 descends further, the first rack bar 22 will slide upward along the first clamping piece 15 in the first clamping group and compress the seventh spring 23. When the first rack bar 22 rises, it will engage with the first gear 21 and drive the limiting wheel 20 to rotate. At this time, the two limiting wheels 20 will convey the outer liner clamped by the first clamping group downward by a certain distance. Then the inserting rod 50 will contact the first clamping piece 15 in the second clamping group, and the inserting rod 50 has a certain inclination. When the inserting rod 50 contacts the notch 19 on the first clamping piece 15, it will push the first clamping piece 15 to both sides. At this time, the first clamping piece 15, the L-shaped rod 12 and the first air cylinder 14 in the second clamping group will all slide along the cross plate 11 and compress the third spring 13. At this time, the two first clamping pieces 15 move away from each other. Then the first motor 7 descends to the limit position. At this time, the two first clamping pieces 15 in the first clamping group also drive the thermos flask outer liner to insert into the bottle mouth part below, and the thermos flask outer liner will sleeve the inner liner inside. Since the inserting rod 50 pushes the first clamping piece 15 in the second clamping group to both sides by a certain distance, the outer liner will not be blocked by the first clamping piece 15 when sleeving the inner liner;

[0080] After the inner and outer liners and the bottle mouth part are sleeved, the two stamping heads 3 are about to descend to the limit distance. Then, the driving assembly continues to drive the stamping head 3 to descend. When the stamping head 3 descends to the limit distance, the driving assembly still presses down the U-shaped rod 17. At this time, the U-shaped rod 17 will slide down along the fixed rod 16. When the U-shaped rod 17 descends, the support rod 18 will push the first clamping piece 15 in the first clamping group and the two L-shaped rods 12 to slide and expand along the cross plate 11. And when the first clamping piece 15 in the first clamping group expands, it will also drive the first clamping piece 15 in the second clamping group to expand. At this time, the first clamping pieces in the first clamping group and the second clamping group are all away from each other, and the inner and outer liners and the bottle mouth part are also sleeved. Then, it can be directly removed. Moreover, the new inner and outer liners above the support plate 4 are also stamped. Then, the driving assembly drives the stamping head 3 to rise again, and then the first motor 7 and the second motor 8 are also reset;

[0081] When the inner liner and the outer liner are sleeved, the limiting plate 6 is in a vertical state, so that the inner liner and the outer liner are coaxial, and thus deviation is prevented when the inner liner and the outer liner are sleeved. And it is not necessary for workers to adjust the positions of the inner and outer liners and the bottle mouth part back and forth, preventing damage to the bottle mouth part and the inner and outer liners when workers apply pressure with a hammer, improving production efficiency and reducing labor costs;

[0082] Moreover, from stamping to subsequent forming, the processing is carried out in the same process. There is no need for transfer and transportation, and the process is integrated, which can also avoid damage to the inner and outer liners during the transportation process.
